Aviation jobs listing service JSFirm reported record postings for aviation professionals last year, with more than 4,000 company members, 60,000 individual résumé members and an average of more than five million Web site hits per month, according to account manager Tonya Salatino. Web site activity has already climbed 10 percent this year, she added. Most of the jobs available are for maintenance technicians, although JSFirm covers all aviation positions, including pilots, managers and engineers.
